Brushless DC electric servo-motor
1 - 4.5 kW, 40 - 300 VDC | QB056 Series Allied Motion

Allied Motion's Quantum (QB) series of housed brushless servo motors are designed for use in precision servo applications that require a standard NEMA 17, 23, 34, or 56 frame size motor.

The QB056 series are standard NEMA 56 interface motors electromechanically optimized for high output power, high torque density, and low cogging torque. Their high power density ratio allows a smaller size motor to be used in many applications, saving space and weight.

Quantum motors are also available as frameless versions for direct machine integration.
